Question

我的ansible yml文件中有3个任务，如下所示。

---

  - name: Instance provisioning
    local_action:
      module: ec2
      region: "{{ vpc_region }}"
      key_name: "{{ ec2_keypair }}"
      instance_type: "{{ instance_type }}"
      image: "{{ ec2_image}}"
      zone: "{{ public_az }}"
      volumes:
        - device_name: "{{ device }}"
          volume_type: "{{ instance_volumetype }}"
          volume_size: "{{ volume }}"
          delete_on_termination: "{{ state }}"
      instance_tags:
        Name: "{{ instance_name }}_{{ release_name }}_APACHE"
        environment: "{{ env_type }}"
      vpc_subnet_id: "{{ public_id }}"
      assign_public_ip: "{{ public_ip_assign }}"
      group_id: "{{ sg_apache }},{{ sg_internal }}"
      wait: "{{ wait_type }}"
    register: ec2

  - name: adding group to inventory file
    lineinfile:
      dest: "/etc/ansible/hosts"
      regexp: "^\\[{{ release_name }}\\]"
      line: "[{{ release_name }}]"
      state: present

  - name: adding apache ip to hosts
    lineinfile:
      dest: "/etc/ansible/hosts"
      line: "{{ item.private_ip }} name=apache dns={{ item.public_dns_name }}
    with_items: ec2.instances

现在我想检查每个任务的退出状态，无论是成功还是失败。

如果任务中的任何一个失败，我的其他任务就不应该执行。

请建议如何写一本ansible剧本

Answer 1

在每个任务中注册一个变量，然后在下一个任务中进行检查。见http://docs.ansible.com/ansible/playbooks_tests.html#task-results

Answer 2

也许playbook blocks并且错误处理是为了帮助你？

Answer 3

这已经是Ansible中的默认行为。如果任务失败，则Playbook将中止并报告失败。您不需要围绕此构建任何额外的功能。

Answer 4

库马尔

如果您想检查每个任务输出，如果成功或失败，请执行此操作，

  - name: Instance provisioning
    local_action:
      module: ec2
      region: "{{ vpc_region }}"
      key_name: "{{ ec2_keypair }}"
      instance_type: "{{ instance_type }}"
      image: "{{ ec2_image}}"
      zone: "{{ public_az }}"
      volumes:
        - device_name: "{{ device }}"
          volume_type: "{{ instance_volumetype }}"
          volume_size: "{{ volume }}"
          delete_on_termination: "{{ state }}"
      instance_tags:
        Name: "{{ instance_name }}_{{ release_name }}_APACHE"
        environment: "{{ env_type }}"
      vpc_subnet_id: "{{ public_id }}"
      assign_public_ip: "{{ public_ip_assign }}"
      group_id: "{{ sg_apache }},{{ sg_internal }}"
      wait: "{{ wait_type }}"
    register: ec2

  - name: adding group to inventory file
    lineinfile:
      dest: "/etc/ansible/hosts"
      regexp: "^\\[{{ release_name }}\\]"
      line: "[{{ release_name }}]"
      state: present
    when: ec2 | changed
    register: fileoutput 

  - name: adding apache ip to hosts
    lineinfile:
      dest: "/etc/ansible/hosts"
      line: "{{ item.private_ip }} name=apache dns={{ item.public_dns_name }}
    with_items: ec2.instances
    when: fileoutput | changed

在代码中，如果任务已更改为True，则在每个任务中注册一个变量，后续任务将执行，否则将跳过该任务。

Answer 5

在第一个任务中，您已将输出注册到ec2。现在使用fail模块在任务失败时停止播放。

实施例

register: ec2

fail:
   when: "ec2.rc == 1"

这里rc是命令的返回码。我们假设1表示失败，0表示成功。

在每项任务后使用失败模块。

让我知道它是否适合你......
